Smart Electronics Kits NE555 CD4017 Light Water Flowing Light LED Module DIY Kit Learning Electronic Handmade DIY Kit
After power on, the 10 LEDs will light up consecutively from left to right, showing the condition of running lights. This kit can control the NE555 timing and CD4017 counting functions intuitively. It is a starter kit for learning timers, counters, frequency dividers, and lantern controllers. At the same time, the kit has good effects, is very interesting and practical, and is also the preferred material for beginners to get started.
This kit is mainly composed of a clock generation circuit and a decimal counter circuit. It is a self-excited multivibrator with NE555 as the core. The power supply charges capacitor C2 through R11, R12, and R13. When C2 just starts to load, pin 2 of NE555 is still in Low level, so the output pin 3 is high. When the current is charged to 2/3 of the supply voltage to C2 through R11, R12, R13, the level of the output pin 3 changes from high to low, and the internal discharge tube of NE555 switches, Capacitor C2 is discharged through R13, R12 , NE555 pin 7 until the voltage across C2 is less than 1/3 of the supply voltage, NE555 pin 3 level changes from low to high again. C2 is charged again, This cycle forms an oscillation. The charging time is: 0.695(R11 + R12 + R13)C2, and the discharging time: 0.695(R13 + R12)C2. Adjusting R13 can adjust the output frequency of the oscillator. The clock oscillation signal from NE555 is continuously added to pin 14 of CD4017. There are 10 LEDs connected to the 10 output terminals of the CD4017. When the 10 output terminals of the CD4017 generate high levels in turn under the action of the clock signal, D1–D10 will be illuminated in turn to form a water lamp effect. Adjust R13 to control the flow rate of LED lights.

Features:
- WATER FLOWING LIGHT ELECTRONIC KIT: This water flowing light electronic kit is mainly composed of clock generation circuit and decimal counter circuit, and self-excited multivibrator with NE555 as the core.
- CHARGE CAPACITOR C1: The water flowing light module’s power source charges the capacitor C1 through R2, R3, and R4. When C1 starts charging, the 2 pin of NE555 is still at a low level, so the output pin 3 is at a high level, when the power supply passes through R2, R3, and R4 to C1. When charging to 2/3 supply voltage, the output pin 3 level changes from high to low.
- ADJUST R4 TO CONTROL OUTPUT FREQUENCY: The charging time is: 0.695 (R2+R3+R4)C1, and the discharge time is 0.695 (R4+R3)C1. Adjusting R4 can control the output frequency of the oscillator. (ie adjusting the R4 to adjust the flow speed of the LED light).
- CYCLE FORMS OSCILLATION: The led chaser diy kit’s inner discharge tube of NE555 is turned on, and the capacitor C1 is discharged through the 7 pins of R4, R3, and NE555. When the voltage across C1 is lower than 1/3 of the power supply voltage, the level of the 3 pin of NE555 changes from low level to high level. The .C1 is charged again, and the cycle forms an oscillation.
- 10 LEDS: The clock oscillation signal of NE555 is continuously added to the 14th pin of CD4017. There are 10 LEDs connected to the 10 output terminals of CD4017. When the 10 output terminals of CD4017 alternately generate high level under the action of clock signal, D1– D10 is sequentially illuminated to form a street light effect.
